Great for the money

Tried the more expensive Auris BluMe HD. Very close. The Bluetooth sound quality was actually quite good. A little more bass from Auris. The Auris also has better headphone sound, but the Auris doesn't have a volume control and the output audio is a bit weaker. Fosi has good headphone volume. The inputs/outputs and displays are placed strangely. The status LEDs are on the back, should be on the front. RCA outputs on the front panel. Many inputs, but only RCA. It would be nice to have an optical

Pros
  • Fingers crossed
Cons
  • Approximately

Portable and efficient

When I saw the packaging I was afraid it would be bigger than I thought, but to my surprise the device was actually smaller than I expected. In my case, being very small is a big advantage as I often move it along with my laptop from my desk (to use a pair of satellite speakers for work) to my living room (to use bluetooth for listening to music). It comes with an AC adapter so I have to power it from my old 5V iPhone power bank (although the cable is included). Setting it up with a USB input…

Pros
  • Handsome
Cons
  • Poor set

This is amazing stuff!

Amazing thing! My friend showed me the little micro amps that are popular these days, but he recommended I buy a DAC because the sound is so-so after streaming from my phone. I thought DACs were digital audio cassettes from the past, but after a lot of research I found Fosi and their little amps and DACs. I had no idea these little boxes could clean up the sound so well! I probably spent three hours playing with it and a fourth plugging my headphones into the Fosi DAC and then back into the…

Pros
  • EASY TO USE AND CLASSIC DESIGN: The Fosi Audio K1 headphone amplifier is easy to set up, no special software, app or drivers required, true plug and play digital audio adapter.
Cons
  • Doubtful purchase for the elderly

Great device with small body

At first I wasn't sure about the DAC IC on the device as it is not the ESS or AKM ICs used in other devices. However, I was pleasantly surprised when I actually used this little guy. Source apps: Netflix phone for movies. Spotify Premium, Youtube Music on the highest settings. The line out was tested with the Schiit Vali2 and acted as a preamp. (Volume control and Bluetooth/USB/optical input can be used.) Coaxial test failed. Bluetooth: Windows laptop, iPhone SE (2016) (headphone out or line…

Pros
  • Fosi Audio K1 as a mini stereo gaming DAC with volume control, not only can bring you superior Hi-Fi sound, but also can be used as a preamp or volume control for your PC/MAC/Computer.
Cons
  • So far so good

Enhance sound stage and picture with Mac laptop built-in sound card

For the past few weeks I've been wanting to get an external DAC. When I saw the Fosi K1 at half the price of the Schiit Modi 3 I had to take the plunge and give it a try. Ultimately, I want a DAC to connect Chromecast audio (optical) to my stereo receiver, speakers, and subwoofer. Unfortunately I'm still waiting for a mini fiber optic cable for Chromecast audio. So for this test I compared the Fosi K1 DAC with the built-in sound card in my MacBook Air 2014 and MacBook Pro 2019. What do you get…
